Abstract

A washer device is provided for a threaded joint formed between two members, preferably two down-hole drill components, each member having a threaded portion and an end surface, the two member threaded portions being engaged to couple the two members such that the two end surfaces generally face each other. The washer device basically includes a generally annular body having a central axis and opposing axial ends. The body is formed of a flexible strip having two opposing ends, the flexible strip being winded about the axis into at least one complete loop with one of the two ends being attached to either an intermediate portion of the strip or the other one of the two strip ends. The annular body is disposable between the two members such that each joint member end surface is disposable against a separate one of the washer body axial ends.
